Where 367 fits
Why 367 is special
Its test pilot barrel-rolled it over a hydroplane race in 1955 without authorisation, which is among the best-documented unauthorised manoeuvres in aviation.

1 × 256 + 0 × 128 + 1 × 64 + 1 × 32 + 0 × 16 + 1 × 8 + 1 × 4 + 1 × 2 + 1 × 1 = 367

Hexadecimal

1 × 256 + 6 × 16 + f × 1 = 367
Read as powers of two: 256 + 64 + 32 + 8 + 4 + 2 + 1 = 367.
In historical numeral systems
Egyptian
3 coils of rope, 6 hobbles, 7 strokes
3 × 100 + 6 × 10 + 7 × 1 = 367. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
6 vertical wedges (sixties place), 7 vertical wedges (units place)
6 × 60 + 7 = 367. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then xi, then zeta, marked as a numeral
tau-xi-zeta + keraia
tau + xi + zeta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
shin, then samekh, then zayin
shin-samekh-zayin
shin (300) + samekh (60) + zayin (7) = 367, written in descending order.
Maya
3 bars + 3 dots (upper, twenties place) over 1 bar + 2 dots (lower, units place)
18 × 20 + 7 = 367. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
